Let's take the simple example of Zomato.com, This site is hosted by "NETMAGIC DATACENTER". But the NameServers of this website are as follows:
ns-807.awsdns-36.net, ns-1061.awsdns-04.org, ns-1737.awsdns-25.co.uk, ns-496.awsdns-62.com
My question is how in the example case the website uses NetMagic Hosting and Amazon NameServers?
